The ED-50 microwave operates at 2.4GHz. This is the same frequency as microwave ovens and home WiFi.
These devices can and may cause occasional false triggers of the ED-50. Microwaves reflect off all surfaces
causing detection inside a room. The higher the sensitivity is set, increased microwave reflection may
occur. Operation or placement in an unoccupied room may optimize performance.
